Comment #2 on issue 977 by [email protected]: DeltaBlue in the V8 benchmarks fails occasionally
http://code.google.com/p/v8/issues/detail?id=977
This is hard to reproduce. We're deoptimizing in Constraint.prototype.satisfy after a conditional branch and taking the wrong branch in the unoptimized code. This hits an alert that we've gotten the wrong answer, "Could not satisfy a required constraint!", though we didn't actually get the wrong answer.
I'll put together a fix. -- v8-dev mailing list [email protected] http://groups.google.com/group/v8-dev
